Looks a bit like the uber-ticks we used to dig out of ourselves in Cyprus. About the size of my little finger-nail and hard as hell to dislodge. I had one burrow into the back of my head once and I could feel/hear the crunching as it chewed away - not pleasant.
Medic had to dig it out with a scalpel - "Ohh.." he says, "it might leave a scar if I do that.." I swore and swore and swore at him until he got on with it.
I mean it's not as if I don't have a few scars as it is, plus the fact that any surgical 'enhancement' to my bonce, however badly done can only ever be an improvement...
